Sub floor ventilation can remove ground moisture from underneath raised floors, creating a drier and warmer sub floor area.
Many pests and building inspectors recommend sub floor ventilation to reduce termite risk. These systems are very effective in homes that experience a continuing musty odour or where there is mould on shoes and clothes in wardrobes or on furniture in living spaces.
Your sub floor area may seem insignificant because it does not form part of your living room. However, the fact of the matter is that this space actually has a high impact on the quality of air you breathe in while you are indoors and may affect your health. Poorly ventilated sub floor areas are often damp. This dampness can result in mould, mildew, musty odours, wood rot and pest infestation in your sub floor area and can also contribute to the spread of mould, mildew and allergies above.
